SPECEIICATEON forming part of Letters Patent No. 432,359, dated July 15,1890.

Application tied Merch 1i, i890.

To all", whom, it may concern.-

Citizen of the United States, and a resident ot haayette, in the countyot Tippecanoe and tate of indiana, have invented certain new and nsei'nlimprovements in Angle-Piston Engines; and I do hereby declareI that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomalte and nse the same. V

My invention relates to improvements in singie-aeting reciprocatingsteam-engines, and is what l denominate an angle-piston enginelf-that tosay, the cylinders and' pistons are connected with a disk on the maindriving-shaft at an angle thereto.

The invention consists in the novel construction and combination ofparts hereinafter described and claimed.

ln the lacconipartying drawings, Figure l is a central verticalsectional view of an engine constructed according te iny invention. Fig.2 is a plan view of the valve. Fig. Si is aseotional view of the saine.Fig@L is aplan view of the steam-chest. Fig. 5 is a section of the same.Fig. (5 is a frontview ofthe cylinders.

In the said drawings, the reference-nmineral `l designates the bed ofthe engine, having two nprights 2 and 3, one of which 3 snpports thedrivin g-shaft, while the other forms a support for the upper part ofthe cylinders. The drivinmshatt supported in upright 3, is provided witha 'disk or driving-wheel 5, firmly secured thereto and having a central.socket G, in which works the hailed end 7 of the shaft S. This shaftextends upwardly at an angle to the plane ot' the driving-shaft. Theupper end of this shaft has its hearings in a diagonal aperture 9 in theupper end of upright Said socket is provided with a. tension or bindingscrew l0 for adj Listing and holding shaft 8 in place. Y

Concentrica-llymounted upon shaft and revolving thereon or therewith isa series ot two or more cylinders l2, each of which is provided withasingle-acting reciprocating piston 155 and a steam-port 1-1.

designates the pistoirrods connected with disk 5 by means ofhellend-socket joints 16 17, and are also connected with the pistons bysimilar 'joints '18 19. The cylinders are preferably fou r in number,and may be formed by taking a cylinder 20, Fig. o, and boring a hole or,aperture 2l centrally therethrough, and then forming the cylinders l2at equal distances apart and concentric with shaft 8. 1Upon the frontface of eylinderQG are formed or provided the bevel gear-teeth 22,meshing with similar teeth 23 on the disk 5, so that said cylinder anddisk inovc in `unison with each other.

The numeral 2l designates the steam-chest, having the inlet and exhaustpipes 25 and 26, the former 25 coninmnieating with the steamspace abovethe. valve, while the latter comninnicates with exhaust-channel 27formed steam-chest, seen in Fig-.3,

28 designates the valve having stem 2U and central bore or aperture 30for passage of shaft 8. This valve is provided with inlet-openil andexhaust-openings 32, and has a handle Iidiy which its position can hechanged to reverse the engine. This valve is stationary and never nievesexcept in reversing.

ing in the position shown in Fig. l, steam is admitted to the uppercylinder, which will canse the piston therein t0 he moved towardA theend. This will cause disk 5, and consequently the driving-shaft, to herotated, and as the disk geared with the cylinders they will rotate inunison. ly this revolution of the cylinders the ports therein arealternatel y brought into coincidence with the inlet and exhaustopenings in the valve at the proper times. The cylinders are so arrangedwith relation to each other that one is always inwerking eondition-thatis to say, just as steam is boing ont olii in one cylinder it is beingsupplied to the next succeeding one, and thus a continuons rotarymovement is kept np. lt will he seen thaJ'oy reason of the space in thesteam-chest z ove the valve wear of the latter is compensated for by thepressure of thev steam and ay tight joint always insured.

Having thus described my invention,what I claim is- In a steam-engine,the combination, with by grooving or recessing the interior of the4 Theo )eration is as follows: The arts he-y inclined shaft S, connected withdriving-disk 5 by ball-and-sooket joint, and the upper end stepped orhaving its bearings in upright 2, the tension or binding screw 9, thecylinders 12, having ports 14, pistons 13, piston-rods 15, and bevelgear-teeth 22,.and the driving-disk 5, having bevel gear-teeth 23, ofthe steamchest 24, having exhaust-channel 27, and the stationary valve28,1mvinginlet and exhaust openings' 31 32 and reversin stantially asdescribed.
